Sharing copyrighted content online without infringing copyright is a complex issue, as laws and platform policies may vary from country to country. Although some people try to use various editing techniques to circumvent copyright detection, these practices are generally illegal and may result in legal consequences. Here are some common ways to try to circumvent copyright detection, as well as the legal and ethical considerations involved: 1. **Pitch or speed change**: Try to avoid automated copyright detection algorithms by changing the pitch or speed of the audio. However, this does not change the copyright status of the content and may still be discovered by copyright holders and require removal or legal action. 2. **Add noise or watermark**: Add noise, watermarks or other distractions to the video or audio in an attempt to make it unrecognizable to content detection tools. Despite this, copyright holders may still be able to confirm infringement through manual review. 3. **Crop or reverse video**: Change the ratio, order or flip the screen of the video to confuse automatic detection. This method also does not affect the copyright nature of the content. 4. **Use small paragraphs of quotation or comment**: The "fair use" principle allows the quotation of copyrighted material under certain conditions (such as educational and commentary purposes), but it is necessary to specifically analyze whether its use meets the standards of fair use under local law. Although there may be technical ways to avoid detection, these methods are usually in the gray area of the law and are not protected by law. Internet platforms often use rights management tools to detect and manage copyrighted materials. Legal compliance and respect for the rights of copyright holders are of utmost importance. When using the copyrighted materials of others, you should obtain the necessary permissions or authorizations. If in doubt, you should consult a legal professional or lawyer.
